Don't bother with "A", you will not be happy.
"B" is a great choice but skip the wet kit and use the carts hydraulics.
"C" and "D" just don't work very well, especially if you are alone. You would need electric trap openers for your trailer to make this option work well.
Another option, although the most expensive of the bunch would be the televeyor express that mounts in place of your existing auger. Very fast and very simple to set up.
One thing to watch if you go the Michels augers is watch your ground clearance going over approaches, don't want to be bending them up. Don't ask me how I know!
